Cart-Mounted High Voltage Surge Generator 4μF 2550J DC Impulse Tester for Cable Fault Location Contractors| XHHV535-4T

The XHHV535-4T is engineered specifically for professional cable fault location service providers and utility maintenance departments who require a self-contained, mobile high-voltage impulse source that can be deployed directly at the fault site — without the setup complexity of separate transformers, capacitor banks, and control consoles.

Conventional high-voltage impulse test setups require field interconnection of separate DC power supplies, capacitor banks, discharge sphere gaps, and safety discharge devices — a time-consuming process prone to connection errors and inconsistent performance. The XHHV535-4T eliminates this fragmentation by integrating all five subsystems within a single mobile cart chassis:

1. Automatic Timed Impulse: Programmable ~7-second auto impulse cycle for systematic cable thumping during acoustic pinpointing — frees the operator to walk the cable route with the acoustic receiver while the generator maintains consistent discharge cadence
2. Manual Impulse: Arbitrary-timing manual trigger via front-panel control — ideal for verifying acoustic propagation in complex urban trench environments with multiple buried utilities
3. DC Withstand Voltage Test: Continuous adjustable DC output for insulation resistance assessment, commissioning tests, and post-repair verification — fully integrated, no external DC test set required

• Cart-Mounted Mobility: Rugged wheeled chassis with integrated handle for single-operator transport across paved surfaces, substation gravel, and construction site terrain
• Impulse-Immune Electronics: Circuit design specifically hardened against the electromagnetic and mechanical shock of repeated 2550J impulse discharges — a distinct advantage over repurposed general-purpose HV power supplies
• Intuitive Visual Monitoring: Large analog-style voltmeter and ammeter plus digital status indicators for real-time HV output, capacitor charge state, and protection status
• Generator-Compatible: Operates on standard 220V AC ±10% 50Hz mains or field generator (>2kW) for remote sites without grid power access
• Overcurrent Protection: 10A low-voltage-side circuit breaker with automatic trip — protects both the instrument and the operator in fault conditions
